Amazing footage by BBC Nature, I had to share:

We have "Planet Earth" queued up for the holiday so we can revisit this classic over a period of days and avoid the tripe that the networks are selling as "classics".turbo said:I love David Attenborough's voice! I bought the BBC version of Planet Earth just because he narrated it - not the US Susan Sarandon version.

A 'Brinicle' ice finger of death, also known as a "sea ice stalactite", is a formation that occurs when extremely cold and salty water sinks to the bottom of the ocean and comes into contact with warmer seawater. This creates a brine-filled ice structure that extends downward, resembling a frozen finger.
A 'Brinicle' ice finger of death forms when extremely cold and salty water sinks to the bottom of the ocean and comes into contact with warmer seawater. The difference in temperature and salinity causes the formation of a brine-filled ice structure that extends downward.
'Brinicle' ice fingers of death have been observed in polar regions, particularly in the Arctic and Antarctic oceans. They are most commonly found in areas where sea ice meets open water.
The size of a 'Brinicle' ice finger of death can vary, but they can grow up to several meters in length. The thickness of the structure can also vary, but it is typically around a few centimeters.
While the formation of a 'Brinicle' ice finger of death may seem ominous, they are not considered dangerous to humans. However, they can have an impact on marine life as they can freeze and trap organisms that come into contact with them.
